What is the trend in atomic mass going down a group?
The atomic mass will increase. As you go down a group in the periodic table the atomic number rises, this increase in the number of protons is accompanied by an increase in the number of neutrons to stabilise the nucleus, and both together lead to an increase in atomic mass.
What properties increase down the periodic table?
Atomic Mass
What is the trend from left to right for atomic mass on the periodic table?
The atomic weight (not mass) increase from left to right in a period.
What does adding a neutron to an atom's nucleus do to the atoms mass?
The atomic mass increase with 1 unit.
What trends do you notice about the atomic number and atomic mass as you move left to right across the table?
they increase by one going from left to right totally a guess

Ifthe atomic number increase what happens to the atomic mass?
Nothing. They are not correlated
Towards the bottom of the periodic table does the atomic mass increase or decrease?
Towards the bottom, atomic mass increases. Atomic number also increases.

The atomic weight (not mass) increase from left to right in a period.

How is the atomic mass number of a nucleus changed by alpha decay or by beta decay or by gamma decay?
The mass does not change much. The Atomic number will increase though.
Why the stability decrease with increasing atomic mass?
Stability depends on to proton/neutron ratio; and this ratio increase with the atomic number.
What number increases in the periodic table?
Both the atomic number and atomic mass. among many other things. They increase the atomic number because the atomic number IS the number of protons in an atom. They increase the atomic mass because the atomic mass is the number of protons + neutrons in an atom. Basically the main two things..
What is atomic mass and what relationship does it have with the periodic table?
The atomic mass of an element is based on the number of nucleons (neutrons + protons) in the atom of the element. It is usually the weighted average of the atomic masses of isotopes of the element, weighted according to the abundance of the isotopes on earth.In most cases, but not all, the atomic mass of an element increase as the atomic number increases.
What ordered pairs of elements shows an increase in atomic number but a decrease in average atomic mass?
this happens with argon and potassium, and also with cobalt nickel. fun stuff.
